hi guys Kirk and Jayson here with Kirk Giordano plastering, today I want to explain something that
we get a lot of calls about and usually people from other states call us and say gee Kirk you
did a video one time and you showed that everybody should gap the plywood if you're gonna go stucco I
want to clarify what I said before now I notice guys this particular addition is going to have
stucco apply and there are no gaps in the plywood generally guys you got to put in eighth of an inch
why that allows for in the heat the weather the Sun will heat up a wall and granted that wall
will expand a little bit and that's why you gap the wood because the plywood could expand the
studs could expand they could twist and all that stuff so if you gap it you allow for the movement
and what causes movement besides the plywood being just set together extremely tight well
there's about a hundred things that cause this movement such as these doors these doors are
going to open and when they shut they're gonna go Bulova baboom they're gonna slam and vibrate that
calls this hairline cracking but that usually causes a cracking that's vertical up and down
every window and every door it'll be vertical usually what else causes cracking we'll just
name the few biggest cuz it take me a half hour to explain all the stuff that causes cracking is
rain rain will saturate the ground lift a house after 20 days of solid rain it'll lift it that's
just the nature of it we're on a busy street cars driving back and forth settling this wall
right here when we put stucco on it even though we use stucco that says it's crack resistant when
you put it on a house that house windows doors vibration wind weather cars going by foundation
settling it's crack resistant if you could you can put the stucco in midair but the minute you
have movements such as putting it on a house and this house is moving people walking inside that's
vibration vibration causes cracking it's like kryptonite to Superman you can't have by Bray in
a house but let's face it guys a house is going to move people walking inside frigerators all kinds
of stuff getting back to the gapi okay we are in Oakland now this fella did a nice job but he
didn't got the plywood and if you're doing wood I'm not certain if you have to get the plywood
but if you're doing stucco you should gather my buddy Jerry puzzle goes around the country and
explains all of this stuff he does seminars he's a consultant works for BMI or sicker now they're
they turned over but each tells everybody around the country gap your plywood for stucco but this
one is not how do you handle it is it the end of the world no it's not the end of the world guys
because in some areas the heat is so drastic like we're in Oakland it's cool we're on the the back
of the house the north side it's not even going to get any Sun south west side is where the Sun
usually hits a wall and we got about ten really hot days here what's really hot days if you guys
are in the UK or in Livermore or you guys say what do you consider hot I consider hot 100 degrees or
above for 30 days or more that will the heat will bake a wall and it will expand it and then it'll
buckle the stucco right here we're in Oakland we're on the north side Suns never going to hit
it and it really doesn't get more than 90 degrees 80 and maybe six to ten days a year so we're not
too bad but if you if you folks can remember if you're doing stucco gap it here's another
tip guys as far as gapping the plywood if it's not gapped and by the way before I forget this
is at least staggered they staggered the plywood big thumbs up for staggering the plywood if it's
not gapped you could always go with because when these doors open and shut if not gap you could
put an expansion joint most folks don't like these they sell Grossman I don't want it they look too
modern this is a expansion joint with a half-inch this is an expansion joint with a solid edge this
you paper a wire and I can put this one right here right where the door is and on that opposite side
of the door and the other one it'll look good and that helps with vibration because there's
the plywood is not gap again guys that stuff is not the end of the world but if you're in an area
say like Arizona Florida and you get constant heat it is a big deal because people send me
pictures and they I'll see a horizontal line and I'll see about an eighth of an inch gap to
a quarter-inch and I'll ride away I'll say that's the the plywood was not gap dicks though the heat
was on it and baked it and then expanded and it busted and tweaked the stucco a bit so anyway
I just pointed out everything is a matter of improvising like say he doesn't have any rings
right here so the homeowner said stick some wires out and what we'll do is we'll pay for it we'll
take the wires through it we'll pop these rings on it put some polyurethane around it it's all
about improvising when you're doing stucco guys we do it all day long we get to a job and you
just improvise but if you can gap it for stucco and and forget about not gap in it that's only if
you're doing wood but anyway guys I see it often and for all you folks who I think it's the end
of the world you call me in a panic it's not you could put an expansion worst-case scenario anyway
